BiCMat members

The Biobased Colloids and Materials (BiCMat) group researches the fundamental and utilization aspects of renewable resources, including lignocellulose, proteins and other biopolymers. Here you will find the individuals (past and present) that make up the BiCMat research group. Each member of the group has their own research and area of expertise, so be sure to find out more about our researchers below.

Group leader

Orlando Rojas

Prof. Orlando Rojas

I work with my team to uncover solutions that nature may provide to fulfill our material needs, by using, sustainably, resources that we find around us, including plants, marine shells and animals as well as biomass waste. Most of our work deals with small objects (colloids), including fibers, particles or other things with shapes that are not well defined. I hope to find disruptive ways to create positive societal impacts and to better our lives. I hope you have similar interests. If you do, I am more than open to collaborate and join efforts.

Academy Fellow, Energy harvesting

My research focuses on next generation solar devices that could prepared using easy manufacturing methods and cheap materials. Besides development of novel materials for flexible solar cells and up-scaling the technology, I study the lifetime issues of these technologies and sustainability of the approaches. Regarding the latter topic, my research lies in utilizing abundant and renewable materials such as wood-derivatives. Overall, I am interested in how increase of renewable energy production changes the future energy systems.

Biocolloid-stabilized emulsions, food emulsions

My research is focused on the development of high-performance of emulsion system and product based on the naturally-derived materials. The label-friendly emulsions can be used in many fields that closely related to our daily life, such as foods, personal care, cosmetics. For future collaboration, the main point should be concentrated on finding a better and easier way to manufacture all natural emulsion systems.

Lipid chemistry

Lipids in biomaterials is the topic of my deepest interest. I have worked within several different projects related to the lipids (determination of polar lipid partitioning in the dairy processes, production of microbial biodiesel from natural resources, production of health beneficial lipids by microbial means, understanding on the lipid metabolism of yeast affected by external fatty acids, examination of the cereal lipid behavior during processing, etc.). I am capable of carrying out various lipid analytic procedures and can apply the knowledge on different lipid systems. Please contact me if you would like to discuss the biobased lipids!

Separation of biocolloids, MFGM

I am a Doctoral Candidate in Aalto University and I hold a Master's degree from Food Sciences. As part of my PhD, I work with dairy innovations. In particular, I study the fractionation of milk and deployment of its lipid components and side streams. My aim is to expand the deployment of natural and functional ingredients and replace additives in food. At the moment, I have three peer-reviewed publications and more coming soon.

Superabsorbency and 3D printing

I am PhD student in the department of bioproducts and biosystems. I work in Biobased colloids and Materials research group (BiCMat) and I have currently two projects on going about fiber-based super-absorbents and also 3D printing of lignocellulosics.

Structural color with CNC

In my research, I use tiny nanoparticles manufactured from a highly abundant and sustainable bio-resource, wood. They assemble into interesting nanostructures that resemble the DNA helix. Uniquely, this creates structural colour with the potential to replace conventional toxic colorants. I engineer the creation of these nanostructures to be applied as cheap coatings providing colour and durability.

Particle co-stabilized foams

I'm a PhD student working in colloidal chemistry with renewable resources (cellulose, hemicellulose, lignin, chitin, bio-surfactants, etc.). My current research focuses on foam-related mechanisms (Foaming property, stabilization) and potential materials. By incorporating air into foam-based materials / systems, I could make light-weight materials with appreciable strength and insulation properties; and achieve efficient production with less raw materials and energy but more air (eg. foam forming fabrics). To further exploit foam-based materials / system, I would be interested in collaborating and working on bio-mimetic foam structure for functional applications in the future.

Smart nanocellulose films

I am a doctoral candidate in Aalto University studying patterning of nanocellulose films and bioactivity. My expertise areas involve surface modification of renewable materials and controlling of non-specific protein adsorption. My studies have given me a broad understanding of wood chemistry but I have especially gained experience with cellulose nanofibrils and nanocrystals.
